Problem Solving CAPTCHA plugin for cpg1.5.x
« on: October 09, 2013, 10:32:17 am »

This plugin replaces the built-in Coppermine CAPTCHA with custom questions your users have to answer (e.g. "Write cat without an a"). This plugin doesn't include any questions. You can add, edit and delete your questions with the config button, which will appear in the plugin manager's "Extra:" field of the plugin.

Hello André,

I have a question,

There is possibility that a spam bot interprets an image file (png, jpg) with either a text or a number, and enter it into the confirmation box?

Regards.

Sorry, but I don't understand what you're asking for.

I like this plugin,

So visually I preferred to put an image to the confirmation response.

I replaced:
Code: [Select]
$question ['text'] for an image file:
Code: [Select]
<img src="example.png" align="middle" border="0" alt="" /> This image contains the answer to enter in the confirmation box.

A spam bot can know that answer, which is in the image?

Regards.

I assume you're asking for a picture CAPTCHA? E.g. the picture displays a dog, house or flower and the user needs to enter this in the box?

Exactly, your idea is much better even.

I had thought just a number. Images attached.

I ask because I have doubts if this is not very safe.

Regards.

I don't see a reason for your request, as the built-in CAPTCHA feature of Coppermine already provides that functionality (characters instead of digits). See http://coppermine-gallery.net/demo/cpg15x/captcha.php

There must be some problem somewhere, because it does not render the original captcha image.

But this is not really worrying as I can use the recaptcha plugin or this plugin.

I like your idea of ​​a dog, house or flower. I'll think I'll do.

Thank you so much.

Does anyone have any experience whether using this yields less or more spam than reCaptcha?

Well after using this for a week my spam has dropped to zero. I was only getting 4 or so a day using recaptcha, but this is great! (Hope I installed it right and people can actually leave comments!)

I don't know why this is, as this plug-in is easier to solve than the recaptcha, but I am grateful - thank you André.

Is there any way to increase the number of Captcha characters to allow more then 5?

Is this question related to this plugin or to Coppermine's captcha feature?
